This is an interesting carrier running off of Cingular's postpaid (read every GSM in the US) network. Text is free to receive, 10 cents to send. Voice has three different plans, or rather two types of plans, one with two options:
1) 20 cents a minute flat rate
2a) 50 cents per day the phone is used for a voice call, 15 cents outgoing, first 100 incoming minutes per month free, then 10 cents a minute
2b) Same as above except $1 a day the phone is used for a voice call and 250 free incoming minutes per month
The phones are expensive but there is an OK selection. They have the Nokia 2600 and 3200, as well as a the Motorola v180 (aka XEna) and Razr, at $50, $130, $100 and $300 respectively. So if you don't like Tracfone's SingleRate phones, or don't want to hunt for deals all the time, XE Mobile is a good choice.
